Lanistes carinatus: for biological control of biomphalaria Alexandria snails II biological features

ABSTRACT

The present work was designed to study the biological features of the ampullarid snail L. carinatus especially its bacteriology and nutritive value since it is consumed locally by some people especially during summer time, after lightly processed. L. carinatus snails were collected from a randomly selected irrigation canal in Khorshid village near Alexandria. The snails were subjected to bacteriological isolation procedures using various culture media and also for biochemical analysis to review its nutritive value. The obtained results showed that 70% of the snail samples were positive for Ps. aeruginosa, Strept. faecalis and Cl. perfringens. While 30% were positive for Esch. coli and Aerobic spore bearing bacilli. The results also revealed that the chemical composition of the snail was moisture [83.38%], total solids [16.62%], crude protein [76.07%], crude fat [7.80%], carbohydrates [13.89%] and Ash [2.24%]. It is nearly similar to that of Boltifish
